Please expand on this... There was a big thread on this where someone thought installing an exhaust caused their differential to fail, and someone else proved that there was no relation.

Not saying you're wrong, but I hate to see misinformation being spread out there...

There are two bolts on the diff that hold up the exhaust. Some people when re installing the exhaust forget to put those nuts back in to secure it. I have no idea if this is directly related to the diff problems that people are talking about but just telling you what i know.

I bought a used Dinan axle back from a forum member and loved the improvement over the stock exhaust as well as the black tips. When that gets too quiet, add a Challenge Street Pipe. Used Dinan for $1500 + Challenge Street pipe for $995ish is the best sounding exhaust without messing with CEL's and such without being too LOUD. If you wanted LOUD, there are 20 different options that will deafen you.

I have had the M Performance Exhaust for several months. It looks great and sounds better. Love the sound...to the extent I do more open windows/roof driving to listen to it...even up to 88 degrees outside temp!

Yep, I installed my Gintani so I know exactly what you're talking about. From what I was reading in that pretty long thread, it seems that these nuts simply hold the exhaust up and have no effect on the diff at all. Of course I put them back on properly, so I'm not worried, but I'm wondering if there are people out there freaking out over nothing and people perpetuating misinformation. Figured I'd try to save some people the future ulcer development

Rated///M- you must must go for the M Performance exhaust - before taking delivery of my M3 I wanted a mod which would make this M3 stand out from the rest. I ordered the part then cancelled, then went onto you tube to listen to it, then ordered it again. m division pulled out all the stops on this one. Made of Inconel,2 year man warranty, 18 kg lighter than stock, no drone unless youre in low revs on 4th, but this too is minimal.Performance BMW magazine features it this month and has nothing but good stuff to say about it.the cold start sizzle makes me grin every time.let me put you in the picture-- I guy with his wife and kid walked pass the car at a Mall in an underground car park as I started it up. I noticed the guys head turn and thought , well it's just another one of those looks.i noticed him turn around again in my rear view mirror.i continued on my way out of the Mall but stopped on one side to fiddle with my iPod.Cruzin pass me is that guy in a white 2012 frost edition competition m3. I know that e sound got his attention .go for m perform pipes- u won't regret it

I thoroughly enjoy my exhaust...no drone, awesome rumble-ly cold start (sets off some losers' alarms in the garage at work), roars as you step up into the showtime RPMs. I'm more a discrete person...I don't want to sound like a honda ricer at stoplights during the afternoon stop and go, but enjoy the sound when I open it up.

Love my M perf exhaust. My GF thought it was a huge waste of money when I told her how much it was going to cost me. When my car came in, the techs weren't able to install the exhaust until the next day so I picked the car up and we drove around without the PE.

Got the PE installed on the car the next day. Turned it on and wow. Drove around and lots more *wow*. By the time we got home after the first trip, she had changed her opinion from "waste of money" to "totally worth it".

The only difference it the type of metal. The M-Perf is made of Inconel, which is marginally lighter than the stock exhaust material and resonates (vibrates) at a slightly different rate. I would save the $1,500-$2,000 and do the mod which will get you sounding 95% just like the M-Perf.

Unless side by side the difference is really inaudible, heck even side by side its rough. Plenty of threads on the topic or you can call ACM and get more details.
I do not fully agree.

I heard both side by side, and they do NOT sound the same at all. The M-performance sounds more refined, more exotic. If you are willing to spill the dough, definitely worth it.

However, the OEM mod does sound very good too, awesome for the price.

The M performance exhaust is worth it's price. It sounds fantastic, I've actually had people come up to me in the parking lot at work to tell me how much they love the sound of the car. I agree with the descriptions of it sounding more exotic, that's right on. Don't be afraid to bargain on the price with dealers though.

1. I ordered myself a new V1. What's the best place to put it?

1. V1 - I used it between all my three cars and always put it on the right side of the driver sunvisor but like any device you have to know how to use it...by itself it will not save you...had it for 8 years, and it has save multiple times every year...dont go anywhere without it...false alarms? sometimes but I take any alarm serious...

2. MPERF EXH - I just purchased my new 2012 e92 Frozen Silver M3 DCT ZCP in Xtmas and installed M Performance Exhaust in March 2012...I researched every possible exhaust in the market and this was the best fit for the e92 M3 for all the right reasons = oem and perfect balance sound, no drone. I previously owned an e60 M5 with SS race-performance exhaust with X-pipe, and the M Performance exhaust is AS addictive as that one....and believe me it does not get much better than the S85 V10 engine sound!!!

Somewhat curious why folks are constantly mounting V1 on the passenger side of the mirror. I've got mine mounted just above and to the driver side of the mirror below the tint. Great range and within reach to easily adjust. Mute for false alarms. Turn it up when I've got the music up. Hardwire kit was used. Turns on/off with car.

I got mine installed in the same spot. Perfect location IMO!

I mount on the passenger side as high up as possible yet still below the tint. I can't see it or reach it as easily but I use the the V1 concealed display and the remote audio accessories to solve this. Mounting it on the passenger side of the mirror makes it harder for someone to see it from the driver side window. Also has great performance in that spot.

If you do not have the CD or RA then make sure you mount it where it is easily seen and operated, like you have on the driver side of the RVM. That spot is also as good for performance as the other side of the RVM. For best results in general, mount it high up on the windshield.


Cheers.

1. V1 - used or direct.

2. I think so. Stock exhaust sounds amazing, just too quiet. If you are keeping the rest of the exhaust intact, then the M performance is a great choice.

2.IMO, not at all. Talk with your dealer about honoring your warranty with aftermarket exhaust. I go to Fields and I have extreme modifications (supercharger, full catless exhaust, lowering springs) and they honored my full warranty. A lot of dealers have employees who are enthusiast like all of us, and are pretty lenient with M cars.
For those states the Bel Sti-r is the wy to go. inconspicuous and so far not detectable by the RDDs.

It makes look cleaner while driving (unless you are the passenger), it is a bit easier to conceal from the cop that nailed you-unless he looks through the front window (I've had officers never take a look beyond my window and the rear bumper), and it makes it a shorter shot to the fuse box for hard wire. Other than that, it is just personal choice.
